Abstract
Abstract A snap-on safety closure or cap is provided for containers of pills, liquids and the like which container cannot readily be opened by small children uninstructed in its use but can be easily opened by an adult. The cap snaps in place on the container and thereafter cannot be lifted off the container except by rotating the cap with respect to the container until a cam on the inside of the cap engages a cam on the rim of the container upon which action the rim of the cap becomes distorted, lifts up and allows the fingernail and part of the finger tip to be inserted under the cap''s edge to lift the cap and snap it off.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
236 words
In combination with a container having an annular necked opening and an annular shoulder extended outward therefrom, a resilient snap on cap covering said necked opening, means retaining said cap thereon after snap on but permitting it to be moved thereon in a rotary manner, an annular skirt on said cap adapted to just clear said annular shoulder throughout the skirt''s periphery and with said shoulder being of larger diameter than said skirt, a cam located on the inside of said skirt, and a cam located on said container and in the path of said cam on the cap as the cap is rotated with each cam having an abutment and the cam on the container also having an incline with the incline faced in that direction to receive the cap''s cam upon rotation of the cap in one rotary direction, whereby upon rotation of said cap by hand said cams come into contact and said cam on the cap rides up on the cam as the container distorting said resilient cap enough to raise the skirt in the vicinity of the cams and thus to allow the cap to be lifted by its skirt and snapped off of the container and upon rotation of the cap in one rotary direction its cam meets the incline of the cam on the container and in the other direction the cams abut one another to prevent further rotation.
